Princess Estelle and Prince Oscar steal the show at grandfather's birthday celebration

Princess Estelle and her younger brother Prince Oscar were undoubtedly the stars as the Swedish royal family gathered on the balcony of the Royal Palace in Stockholm to celebrate the monarch’s 72nd birthday. Estelle, six, was adorably pictured squeezing her two-year-old bother’s cheeks and giving him a sweet kiss, while proud mom Crown Princess Victoria looked on. The young Princess and Prince happily waved to well-wishers who gathered in the courtyard of the palace.

Last year, Swedish House Mafia members Axel Christofer Hedfors and Sebastian Ingrosso opened up to HOLA! USA about their royal fans. “Whenever it's his birthday [King Carl] has an orchestra play Don’t You Worry Child for him,” Axel shared. “It’s a bit of an honor that they are coming and appreciating our music,” he added. “It’s an honor, but what’s great about them is that they are also very normal.”
